IMPROVED BBD-BOTTOM.

@Ligt rlgshnl referat tu iirilgese Entert/@Quant mit uniting @mit t tlg sume TO -ALL WHOM IT MAY OONC'ERN .Y Be it known that I, HENRY B. WALBMDGE, of Toledo, in the county of nucas,aud State of Ohio, have invented a new andimpoved Bed-Bottom; and I do herebydeclare that the. following is a full, clear, and 'exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which; i

Figure 1 isa longitudinal section through a bedstead, having my improved bed-bottom applied to it. Figure 2 is a transverse section, takenin a vertical plane through fig. 1, at the point indicated by the red line a: z thereon. v

`Figure 'is a bottom view of the bed-bottom detached from a bedstead. Figure 4 is a side view of the same when folded. Similar letters ofreference-indicate corresponding partsin the several -iigurest l This invention 'relates to a new and useful improvement on bed-bottoms, of thathclass wherein sucking or cloth of any other suitable description is employed for supporting the beds.

v The object of my invention is to construct 'a bed-bottom, so that, while it can be made very cheap and durable, means are a'orded for stretching the cloth, and keeping as tightly stretched as may be found desirable, and also for taking up any slack in the cloth which might occur from long use. i l

The `nature of my invention 'consists in a removable, rectangular, and centrally-divided hinged frame, having a sucking-bottom secured permanently to one end ofv it, and applied to the opposite end of it by means ofA a stretching or takefup bar and button-fastenings, in the manner hereinafter described, so that the sucking can be readily taken up'or letout at pleasure, after which one portionhof its frame can be conveniently employed as a powerful lever, by which to stretch the sacking, and hold it under any desired tension, as will be hereinafter explained. y

To enable others skilled inthe art to understand my invention, I will describe its construction and operation.

The bedstead to which my invention is represented as being applied is made' in `the usual well-known manner, as the improved bLed-bottom which I am` about to describe may be applied toalmost any of the well-known bedsteads, by securing inside ledges a a to the longitudinal rails A A for the frame ofthe bed-bottom to rest upon. The frame of the bed-bottom is of rectangular form, and consists of two longitudinal' sectionsB B,

I which.'are hinged together at or near the mddleoi,l their length by means of hinges'b b, Whi'dhare secured on the upper sides or edges of their longitudinal bars.. This iframe may hel folded, as shown in `fig. 4, 'or it may be adjusted, so as tohave its two sections lie'in a horizontall plane, as shown in gs. land 3. Its ends are con` neeted'together by *means of strong bars C C", which are let into and. secured firmly to the longitudinal rails or bars, as shown in the drawings. This frame is made of such width a-nd length that it will iit snugly within the bedstead for-which it is adapted, and he supported upon'the ledges a a. To the outer edge of the transverse.

bar of the frame-section Bthe cloth D is permanently nailed,'so that itwill allow the cloth to resist con;l siderable strain. The opposite end of this cloth D is nailed to a at bar, c, of such length as to fit between the .two rails of the section B. Thisrilnt bar is introduced inside of a piece, E, and held vrmly'iny place against this piece by meansof a number of buttons, g g,which are pivoted to the bottom side of the cross-bar C, as shown in figs. 1,'2', and '3. It will-be seen that, when bar c is clamped against the piece E by the buttons g, this bar c annot be drawn out of it by any ordinary amount of strain applied to the cloth, yet the bar:c can be'readilyv removed by releasing the buttons g from it. The object of bar c is to allowl the cloth o'i Backing Dto be wound upon or unwound from it for regulating the tension of the cloth uponthe frame.

The adjustment is aected as follows: One end of: the frame is held down in place uponits ledges at a by means of cleats und the opposite end or section B is held down by means of pins t'. These pinsz' are removed and section B thrown np, as indicated in red lines in fig. 1, which will so slacken the sacking as to allow the bar c to be `readily removed from its' place. If the acking should have been too-slack,v the har c'is turned v partly or entirely around, sov as to roll up a proper amount of the saclring upon it.'4 This bar is again returned to its place vand secured 'by means of the buttons y, as before described, when it will be found that itvwill require considerable pressure to return the section Bback to a'horiz-ontal position, in doing which the sacking will be forcibly s tretcheil and tightened. The pins z' being then inserted over the section B into the :side reils A A,

lsection B will' beheld down in place upon its ledges a. Thus it will be seen that moreor less of the seeking' can be readily tak-en upor 'let o`t, as occasion requires, sind that' onefof the hinged-sections of the seekingframe will serve es ztleve'rl to render the operation of stretching the seeking aLfvery siniple endeonvenient one. The'her c sustains the saekingthroughout tsentix'e width,vnnd enablesa. person to keep this eloth- `underfan-y proper tension 'as long aait-is strong enough to withstand the strain.,` It ivill alsoibe seen vthu-1t the frame to which the seeking is -pplied is removable, and that it can be folde so as to reduce it to a compass of :bout

half its length'. :Insteofl of'iising cleats'and pins for' holding th-evframe 1,3l B in place inthe be'dstead,a s described, strong buttonfa'stenings may be employed, fitted in'reees'ses made in the side rails of the beiistendf"Y Havingxlescribedmy invention, what Iv claim afs nein-end desire to secure by Letters Patent, is-

vl. Ajbed-hottom'whieh is eomposedof a. hinged sectional fraude' B B', having the seeking seuredA permanently. to'one section, and applied to the other section by means of a Het bar, c, and clamps g y, suhstehtially as deserihefA i I I 'I 2. Constructing theMseeking-frnme B B', and applying the seeking thereto, in such manner that, while the seeking can be more or'less. slaekened or tightened at pleasure, one section of said fraaie will serve es :L means for foreibly'tightening the seeking, in combnatior with reteinirfg-eleets and removable pins' applied to the bedstead-reils, suhstntially as described.
